BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of interspecific Geranium plant, botanically known as Pelargonium zonale×Pelargonium peltatum and hereinafter referred to by the name ‘Duesalsadar’.

The new interspecific Geranium plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new freely-branching interspecific Geranium plants with semi-upright growth habit and large attractive flowers.

The new interspecific Geranium plant originated from a cross-pollination made by the Inventor in July, 2009 in Rheinberg, Germany of a proprietary selection of Pelargonium zonale×Pelargonium peltatum identified as code number F-03-04-18, not patented, as the female, or seed, parent with a proprietary selection of Pelargonium zonale×Pelargonium peltatum identified as code number Z04-0808-004, not patented, as the male, or pollen, parent. The new interspecific Geranium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2010.

Asexual reproduction of the new interspecific Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2010 has shown that the unique features of this new interspecific Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new interspecific Geranium have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesalsadar’. These characteristics in combination distinguish ‘Duesalsadar’ as a new and distinct interspecific Geranium plant:

-   -   1. Compact, semi-upright to outwardly spreading plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely basal branching habit.     -   4. Freely flowering habit.     -   5. Large red-colored single flowers.     -   6. Good garden performance.

Plants of the new interspecific Geranium differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new interspecific Geranium are more vigorous         than plants of the female parent selection.     -   2. Plants of the new interspecific Geranium have darker         green-colored leaves than plants of the female parent selection.

Plants of the new interspecific Geranium differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new interspecific Geranium are not as upright         as plants of the male parent selection.     -   2. Plants of the new interspecific Geranium and the male parent         selection differ in flower color as plants of the male parent         selection have orange red-colored flowers.

Plants of the new interspecific Geranium can be compared to plants of the interspecific Geranium ‘Duesalsapi’, disclosed in a U.S. Plant patent application Ser. No. 13/373,726. Plants of the new interspecific Geranium and ‘Duesalsapi’ differ primarily in flower color as plants of ‘Duesalsapi’ have light red purple-colored flowers. In addition, plants of the new interspecific Geranium have single flowers whereas plants of ‘Duesalsapi’ have semi-double flowers.

Plants of the new interspecific Geranium can be compared to plants of interspecific Geranium ‘Amri Trared’, disclosed in U.S. Plant Pat. No. 20,245. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new interspecific Geranium differed primarily from plants of ‘Amri Trared’ in the following characteristics:

-   -   1. Plants of the new interspecific Geranium were more vigorous         and had longer internodes than plants of ‘Amri Trared’.     -   2. Plants of the new interspecific Geranium had larger         inflorescences and larger flowers than plants of ‘Amri Trared’.     -   3. Plants of the new interspecific Geranium had single flowers         whereas plants of ‘Amri Trared’ had semi-double flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new interspecific Geranium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new interspecific Geranium plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duesalsadar’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices which closely approximate commercial Pelargonium production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 13 weeks old when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
